Hello , perhaps it is not the right "sub-forum" but i hope moderators will move it
So i found on internet you can remove rust with vinegar , just let ( the rusty iron) in a bottle for a couple of days , if too rusty maybe even more.
But i would like to speed it up a little , the best vinegar has only 5% acid , and in my country it does not sell at shops,
If i remember well , in chemistry class , for any chemical reaction , there was a catalyzator ( or catalyzer ?)
For one thing i know that salt will catalyze electrolysis , is there any hope to make that de-rusting reaction better ?
